Hi, all the required links can be found below the video: Previous tutorials about the modules used, schematics, libraries and codes. The codes provided contain a lot of comments not like the ones shown on the video... Wire your modules and you're ready to go.
Hello!! Great video.🙌 I'm using the same module (sim800l v2) Can u pls tell me what you used to provide power supply? How much current and voltage rating should I provide for it to function properly?
hey are you facing the issue like sending long sentences to gsm but reciving in accurately the words when short messages sent it recieves accurately...is the problem gsm module or is it common?
Hello sir, first i’d like to thanks for the knowledge you’ve shared throughout your website and youtube. I created an over-voltage alarm program that read voltage with refresh rate every 3 seconds. where if the voltage exceeds the set point 420 VAC it will automatically send a SMS. but the problem occurs because the SMS keeps repeating every 3 seconds, so how can i do to make the SMS only sent once at the beginning. despite over voltage condition least for minutes / hour after it.? Thank you sir. I hope you can help me
SurtrTech I have designed a self driving arduino car with an obstacle avoidance system and line tracking. My car can also be controlled through bluetooth or with an IR remote. Do you have any ideas on a science fair project I could do with my car?
Hello Sir. I have checked and it works perfectly. I have modified it as per my requirement. But there is one issue I have found .. Once I switch off the device and start once again the device is not working until I press the reset button of Arduino. Once I press the reset button after that it starts to work. It means every time when we start the device( give the power supply through adapter), first we have to press the reset button of Arduino. " I have checked after sim800 connect to network".
Hello Sir, I got the solution. The issue is created because Arduino is an initialised sim800 module before the module is connected to network. So what I do, first I have monitor the time for GSM to be stable means it connected to the network. In my case GSM takes max. 16 s, So I just write a delay function of 17s in the void setup function very first. During this time period, GSM connects to the network, and then our circuit work properly.
@@Name-ub1kz You can try "AT+CNMI=?" to check the available options, make sure you check the manual for other commands and troubleshooting www.elecrow.com/wiki/images/2/20/SIM800_Series_AT_Command_Manual_V1.09.pdf
I don't know exactly, but as I tested, the moment the whole sequence stops you can start another one again... it always needs to put the module on receiving SMS mode before you can ask for another value.
hello i have one problem with som800l module. i cant recive any sms in android from sim800l. but i can receive sms in old keypad mobile. do you have any solution. if have please help...
Hello, make sure your Android phone doesn't block the unknown numbers or don't you have an app that considers the SMS as a spam... if the module can send SMS to other devices it works well.
Hello, may you be able to make a project of ECG? and display on the monitor screen, and if possible add more temperature sensors and tensimeter sensors... thanks...I need a reference brother🙏
Hello all wirings, codes and libraries are in the link below the video which is: surtrtech.com/2020/01/19/send-receive-sms-using-sim800l-with-arduino-dht11-mlx90614-digitspace-com/
